Mass Fatality Incident [MFI] Law and Legal Definition
Mass fatality incident (MFI) is a situation where more fatal accidents gather than that can be managed by local resources. For instance, when a passenger aircraft crashes carrying 100 to 300 passengers or a building structure collapses on hundreds of people, the incident would probably be considered a mass fatality incident. Mass fatality incident may be either man-made, such as hazardous materials releases, transportation accidents, or terrorist attacks, or they may be the result of natural disasters such as earthquakes, floods, or severe weather. However, when a gunman kills five people, it would probably be considered a multiple and not a mass fatality incident if it occurs in a major city.
